L_DicomSetLayerInfo

#include "l_bitmap.h"

L_UINT16 EXT_FUNCTION L_DicomSetLayerInfo(hDS, uLayerIndex, pGraphicLayer)

HDICOMDS hDS;	/* a DICOM handle */
L_UINT uLayerIndex;	/* layer index */
pDICOMGRAPHICLAYER pGraphicLayer;	/* pointer to the layer attributes structure */

Sets layer attributes for the layer at the specified index.

Parameter	Description
hDS	A DICOM handle.
uLayerIndex	Zero-based index of the layer to be updated.
pGraphicLayer	Structure containing the layer attributes.

Returns

0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

Before calling this function, initialize pGraphicLayer-> uStructSize to be sizeof(DICOMGRAPHICLAYER) and initialize all the structure members.

The index(uLayerIndex) is based on the number of items under the "Graphic Layer Sequence" (0070,0060), for example the index of the first item is zero.
